LOBLOLLY OR NORTH CAROLINA PINE. 73 



inch trees, 15 per cent for 9, 10 and 11-inch trees, and 5 per cent for 12- 

 inch trees to cover excessive crook, waste and breakage. No allowance 

 is required for trees of larger diameters. An average deduction of 10 

 per cent consequently is sufficient for all except very young stands. In 

 practice this loss is covered hy the deductions made in the woods' scale 

 for crook and breakage. It should be allowed however in estimating and 

 volume appraisal. 



Table 32 gives the number of logs 16 feet long, and the diameter at 

 the small end of the top log for trees of different diameters and heights 

 on which the volume tables of the trees are based. 



Table 33 gives the volume in cubic feet of merchantable stemwood 

 (without bark) in trees of different diameters and heights, less than 75 

 years old. 



Table 34 gives the comparative volumes with and without bark, in 

 cubic feet and cords, number of trees to a cord and per cent of bark, in 

 trees of different diameters and heights in stands 35 to 45 years old, 

 Quality II, which may be assumed to be an average site and average age 

 for cordwood stock. The volumes would be less for younger stands in 

 which the trees have the same diameters and heights.
